Generation

# Duration Arithmetic Across Months **Precise Rule:** When adding months to a date, if the resulting day doesn't exist in the target month, the date rolls to the last valid day of that month. **Example:** January 31 + 1 month = February 28 (or 29 in leap years), not March 2 or 3. **Why It Matters:** This prevents cascading errors in financial calculations, subscription billing, and scheduling systems. Using naive day-counting (e.g., +30 days) instead of month-aware arithmetic can cause dates to drift across month boundaries, leading to incorrect billing cycles, missed deadlines, and data inconsistencies in production systems.
